This study analyzes an economic efficiency of environmental friendly farm and conventional farm using the data envelopment analysis (DEA). We compare the economic efficiency of Environmental Friendly farm and Conventional farm. We also analyze the effects of some explanatory variables on allocative efficiency (AE), pure technology efficiency (PTE) and scale efficiency (SE). In the case of strawberries farm, environmental friendly farm has higher overall efficiency (OE) than conventional farm. But tomatoes farm has higher overall efficiency (OE) than conventional farm. And We measure returns to scale of farms. Most strawberries and tomatoes farms showed Increasing to Scale (IRS).

This paper analyzes economic efficiency of strawberries and tomatoes farms using the data envelopment analysis (DEA). We examine how production characteristics and farm size affect overall efficiency (OE), allocative efficiency (AE), and technological efficiency (TE). We also survey sample farm households from the Farm Income Investigation database of Rural Development Administration to investigate management and cultivation techniques and to analyze economic efficiency by technique. Implications for improving efficiency are suggested in the conclusion.

This study analyzes an economic efficiencies of apples, pears, and grapes farming. We evaluate an annual economic overall efficiency (OE), allocative efficiency (AE), technology efficiency (TE), pure technology efficiency (PTE), and scale efficiency (SE) using data envelopment analysis (DEA). We also measure returns to scale of farms, and the change of technical efficiency of frontier farms. Lastly we estimate the effects of some explanatory variables on allocative, pure technical, and scale efficiencies.

This study evaluate examines the efficiency and the improvement measurement of Oilseed crops (Sesame and Perilla). For this purpose, In the first stage, this study analyzes the current conditions of oilseed industry. In the second stage, this study evaluates the efficiency and super-efficiency of environmentally-friendly agricultural product producers. The result of this study show that: (1) Changes in annual wholesale price of Sesame and Perilla; (2) An efficiency and ranking of environmentally-friendly product producers; (3) The solutions and improvement measurements for inefficient producers

오늘날과 같이 급속히 변화하는 기업경영 환경에서 조직이 생존하고 번영하기 위해 기업의 경영 성과를 향상시켜야 하고 이를 위해서는 생산성 또는 효율성을 꾸준히 평가할 필요가 있다. 최근 컨테이너터미널 업체수는 증가하였음에도 불구하고 물동량의 증가가 미미하여, 물동량 확보를 위한 컨테이너터미널 운영사간의 선사 및 화물유치를 위한 경쟁이 치열해지고 있다. 이러한 경쟁은 하역요율이 하락하고 컨테이너터미널 운영사들의 경영수지가 악화되고 있는 추세이다. 따라서 본 논문은 DEA(Data Envelopment Analysis) 방법론을 이용하여 국내 컨테이너터미널 운영사의 경영 효율성을 비교 분석함으로써 컨테이너터미널 운영사의 경영 효율성 수준을 파악해 보았다. 본 연구는 기업 경영 분석에서 산출기초가 되는 가장 중요한 인건비, 임대료, 관리비용과 같은 비용항목을 투입변수로 선정하였으며, 산출변수에는 매출액, 영업이익을 선정하여 2009년도 경영 효율성을 분석하였다. 분석 대상들은 효율적인 컨테이너터미널 운영사와 비효율적인 운영사들로 구분하고, 비효율적인 운영사는 상대적으로 얼마나 비효율적인지에 대한 정보와 경영 효율성을 갖추기 위한 개선 방안을 제시한다.

This paper evaluates the technical efficiency of organic farm management practices and studies its main determinants in Hongdongmyeon of Hongsung county, Chungnam province. The analysis is performed in two stages. First, the efficiency is measured via the nonparametric “Data Envelopment Analysis” (DEA) technique. The DEA models are constructed not only to assess the overall technical efficiency of organic farming practices but also to evaluate the management efficiencies. In a second stage critical determinants of efficiency are determined using a Tobit model. In this analysis the focus is on technical and socio-economic variables. The analytical results show that technically efficient farms is about 13 percent and the mean technical efficiency is found to be 0.73 indicating that many farms are not operating at an efficient scale.

이 연구는 한국 쌀생산의 효율성을 경영규모별로 파악하고, 영농규모 확대를 통한 쌀생산의 효율성 중대 가 가능하다는 가설을 검정해 보고자 하였다. 이 분석에 필요한 기술적 선도농가들의 생산함수인 프런티어(frontier) 생산함수를 구하기 위해서는 교 란항의 정보를 이용할 수 있는 확률(stochastic) 모형아 바람직하고, 아울러 경영규모별로 규모의 효율성을 파악하기 위해서는 레이 동조(ray-homothetic) 함수가 적절하다. 따라서 여기에서는
